Subprojects and Milestones are both special kinds of projects.

Subprojects are like projects but are associated with a parent

There is quite a long discussion about this on the upstream issue
tracker -

Milestones are projects which are meant for tracking releases. A
project can only have one milestone at a time and importantly the
parent project is shown on the UI with milestones.

I took some screenshots to show how they show up in UI.

They are not very mature and I expect their usage will be refined in
the next iteration. The UI for selecting projects could certainly be
improved rather than presenting a list of amorphous labels.
